A man has been left with a bite mark in his ear after he was robbed and assaulted by three men who stopped him and asked for a cigarette.

Police are investigating the incident, where the trio assaulted the man as he was walking along Sixhills Street in Grimsby, at around 12:15am on Wednesday June 14, close to B&Q, before stealing his wallet.

Officers say a man on a bike approached the victim and asked to use his mobile phone to send a text. The man refused and started to walk away when he was approached by two other men, one riding a bike and carrying the second.

After asking for a cigarette, they attacked the victim, stealing his wallet and leaving him shaken with a bite mark on his right ear.
